(* Convert to the offset/gain setting mode *)
IF(Var_Flag=TRUE)THEN (* Var_Flag ON *)
MOVP(TRUE,1,Var_ControlData); (* Sets mode *)
G_OFFGAN(TRUE,H00,Var_ControlData); (* Converts mode *)
END_IF;
IF(X0A=TRUE)THEN
END_IF;
(* Convert to the normal mode *)
IF(Var_Flag=FALSE)THEN (* Var_Flag OFF *)
MOVP(TRUE,0,Var_ControlData); (* Sets mode *)
G_OFFGAN(TRUE,H00,Var_ControlData); (* Converts mode *)
